Seven Unanswered Calls

My thumb was hanging over green.
The screen went dark before I chose.
Maybe that's what saved me.
Seven missed calls, and I still know your number by heart.
Seven missed calls, and that's the dangerous part.
Some people leave without a warning.
Some never really leave your heart.
Seven missed calls, and that's the dangerous part.
2:17 In the morning, city lights against my wall,
Your name fading from my screen.
Seven missed calls.
